Can I do CS along with CA

Hello every one.

I've cleared both groups of PCC(June 2009)

Now i am having sufficient time so i am thinking of doing CS or CWA(CMA) along with CA.

Can anyone tell me which course has a better combination and prospects with CA.And whether i will get any exemtion for clearing CA-PCC.

Thanks in advance.
